FLYWHEEL.

vApplication led SeptemberrlO, 1926. Serial No. .13 4,G43."7

This invention r-elates Vto newr and useful improvements in fly Wheels.vv Y Fly wheels Vare generallyconstructed with Y spokes radiating fromthe hub portion of the wheclto therim'portion thereof.Y In order toprotect theworkman from getting Y his hands or ,clothing caught betweenthe spokes of the fly wheel, itis customaryto either enclose the flywheel in a cage'or cover the spokes with ajeover .platejplaoed againstone side of the wheel.` Insomerinstances ywheels are formed With'anintegral solid Vweb portion instead of spokes.v f In the operati-onkofpresses andothermachinery, it is very frequently necessary to operatethe machine by hand. `This isusu#l ally done bythe 'Workman grasping.the spoke olI the fly wheel with one hand and rotating said wheel;W'here the .fly -wheel is enclosed in a cage itis necessary toopen thiscage to provide access vto the lwheel thereby Wasting a great deal oftime. vFor this reasoncit is more .desirable to use a fly wheel whichvis exposed'and'in .which Vthe f spokes are covered by' a plate placedthere- Y against. However, by using thisplate or lforming the fly WheelwithV an integrall solid 'web portion, the workman is greatlyhandrcapped in manually operating the machine as no means are provided toenablel him to get a goodv hold on the wheel. i t

.1t yis the object ofthe present-invention to provide means carried bythe cover plate ,ot the web portion vof the flyovheehsaid means beingvprovided on the far side with respect to the directionA of rotation ofthe flywheel with a suitable recess so asxto` en. i able the workman toobtain a Asuitable hand hold `on the wheel when it is desired to manduall-y operate the latter, This means or'handle has its remaining sidesformed sloping or Y curved so as to prevent abrupt projecting facesbeing presented in theline'ofrotation of the Wheel. i Y j Other objects4of the invention 4are ,to provide a member attachable to the lywhe'elor a cover plate for the spokesV thereof, said member beingprovi dedwith arecesfs to forin a suitable handle 'disposed ina Vpredeterminedrelation with respect tothe direction of rotation ot sai d flyk wheel.vThe.,remaining surfaces ot said Amember Vare curved-so to mergewith theflanged portion thereof.

Further objects of the invention. are to provide a fly wheel having aclosed web portion extendingqbetween the hub and rim para@ of 'anniwheel and provided with a series vofradialhandlesarranged on said ,webportion equi-distant about thea'Xis 'of y l f presented in the line ofrotation said ily wheel and havingQgaduallyl curved surfaces Y ofsaid'fly wheel thereby eliminating abrupt fr laterall proj ections .on said[ly wheel.

W ith-these and other objects in view, my invention consists Voitce'rtain'novel features of-co1`istruction and arrangement of parts,hereinafter more fully' described and claimed, and illustrated in theaccompanying4 drawings, in which# y 'Figure 1 is an elevational View ofaV fly wheel constructed in accordance .with my invention."A y l Figure2 isa 'orizont'al crossvsectiontaken i y online2-'- 2of Figure l. j A -vl I i.

A Reierring by rnumerals Vto the accompanying drawings, 10 indicates lashaft on which .ismounted a fly-wheel 11, the latter consist-r ingof ahub po'rti'o'l'r12, rim portion 111 and spokes 1'5 all of which mayybeef the usual construction.

"IA cover plate 16 is placed against one side 'of spokesylland'isprovililed with a central openii'igv 17 .for accommodating hubportion 12. This plateis of suitable Asizeto extend within rim 121'.'V'Plate 16V isfsecur'ed imposi- ,tion yby means of U-bolts 18 which havetheir terminalportions 19 extending through openings 20 in plateljtransversely of.. and on each side of each spoke'l. Atransverse member21' yis apertured .near itsVV ends for the reception of the threadedends ofgpqrl tions- 19 and clamps coverp16 .against ,the spoke ,15.4Each memberffl is secured'inposition byvv means of'fasteningdevicesornuts aan 22 screwed on the ends of'poitions 19; They l ends ofportions .19" terminate substantially flush with said nuts Vsojastoeliminate ab; rupt projections on the flywheel. u However,

plate A16 being placedV against the outside-of.

spokes 15,1nu'ts 22 andmembers21 are disposed on the inner sideofVthetly .wheelade jacent to the press or other machine with whichsaidliy Wheel is. associated and conl lo sequently there is no danger ofinjuryftothe workmanfrom the above.` Plate 16 closes spaces 23 formed byspokes 15 so that all danger of the workmans hand or clothing beingcaught between said spokes .is thereby eliminated.

To permit ready manipulation of thefly wheel by the workman, I provide aseries of handhold members 24 which are fixed to plate 1G by suitablefastening means 25 and are spaced on said cover equi-distant about theaxis of fly wheel 11. Each member 24 isprovided at its base with. amarginal flange 2 6 by meansof which said member is secured toplate y16and the body portion o'f said memberw 24'co'nsists of a wall 27 whichcurves upwardly and rearwardly so as to form a recess 28 foraccommodating the fingers of the operators hand and the rearwardlypresented edge of said wall is shaped soH as to form a suitable handleportion as indicated at 29.V Each member 24 is disposed on cover 16 soas to dispose handler portion 29 radially on said wheel. and present itrearwardly with respect to the' direction of rotation thereof. The outerfaces 43() and 31 of vwalll 27 are curved'and Vmerge with flangeVQG-thereby eliminating sharp corners and projections and ypresentingsmooth surfaces in the line ofrotati'on' of said wheel.

In vthis manner suitable means are provided toenable thek workman tomanually operate the 'fly wheel without any difficulty and at the sametime all vabrupt.surfaces or projections are eliminated sothat there isno danger of the worlrmans hander clothing being caught therebyY whenthe wheel is rotated. y

In the form vshown in Figure 6, the Hy wheel 32 is formed with asolidweb portion 34 which extends between hub portion 35 and rim portion 36.A series of hand-hold members 24aiis fixed to web portion 34 at suitablespaced intervals andv furnishes the means for manually operating saidfly wheel..

In this manner I provide simple and inexpensive means for covering thespaces Vbetween the spokes thereby providinga safety Yguard so that theworkman cannot y.getv his hand caught therebetween and atA the same timesuitable .means are provided on said covertoallow easy manipulation ofthe wheel.

While have shown and described the preferredform of my invention, it isob vious that various minor changes or arrangements could be made in the.cover and in the handhold members without departing from the spirit ofmyinvention.

I claim:

1. A Hy wheel, a plate extending between the hub portion and the rim ofsaid fly wheel, and arseries of hand-hold members fixed to said plateand spaced equi-distant about the axis ofsaid wheel, each of saidhand-hold members being formed with a shoulder portion presentedrearwardly with respect to the direction of rotation of said flywheeland having its forward and end faces inclined Adownwardly and forwardlyand terminating in marginal flanges adapted to be secured to said plate.

3. The combination of a fly wheel having a portion extending between thehub portion and the rim portion thereof, and a series of hand-holdmembers having Vhandle portions presented rearwardly with respect to thedirection of rotation of said wheel and spaced laterally from saidportion, each of said hand-hold members being provided with vmarginalflanges disposed forwardly and on the sides of eachk member, theV frontwall and the end walls of each member being inclined downwardly fromsaid handle portion to merge with said flanged portion therebypresenting smooth surfaces in the direction of rotation of said wheel.

4. In a fly Wheel construction, a plate adapted to be placed against oneside of ra fly wheel so as to cover the spokes thereo-, said platebeingprovided with an opening toA accommodate the hub portion of a flywheel, means for detachably securing said plate to said spokes, andaseries of handhold memberssecured to said `plate equidistant about theaxis thereof, each of said members being provided with downwardlysloping front and end walls so as to present smooth surfaces in thedirection of rotation of said iwheel, therev being a handle portion l iliis

and front andy endl faces curved. laterally from said base and having arecessed rear side so'as to provide a suitable handle portion disposedrearwardly with respect to the direction of rotation of said wheel.

In testimony whereof I hereunto' affix my signature this Llth dayofSeptember, 1926.
